' TIME EGG-BOILER.

:To all whem-it may concern:

Beit known that I, HORACE H. CHEs- BROUGH, 8. citizen of the United States, ;resid ing at Seattleyin thecounty of King and State. of Washington, have invented certain new and useful Improvements in Egg-Boilers,

of which the following is aspecification, ref

erence being had therein to the accompanying drawings, in .which,-

Figure 1 is aside elevation of an embodiment of my invention with the egg-receptaclethereof shown removed from the cookingcompartmentj Fig. 2'is' a plan viewof the same with the egg-receptacle in'cooking' posit ion. Fig. 3 is a vertical section'taken on line a: a; of Fig. 2-'.- Fig. l is an enlarged longitudinal vertical section of aportionrof the invention, wherein the illustrated parts are shown in thepositions assumed whenthe sev-' eral parts are as represented in Fig. 1.' Fig.

' 5' is a cross-sectiona view throughy y of Fig.

l mentary detail view in perspective of tion of the operating mechanism. The objectof this invention is, to provide in compact and'neat form convenient and reliable means for boilin eggs to any predetermined amount of-har ness by the'use of devices for immersing the same in the cooking-' ,water, retaimng them therein a sufiicient a time to attain such result, and then removing I them automatically fromthe water.

a The invention consists of the novel con- ,to saiddrawingsstruction, adaptation,- and combination The reference-numeral 1 designates a casing which is divided by a transverse partition '2 to provide at the front end a compartment 3 for the'receptionof the actuating and controlling. mechanism and at-theother end a compartment 4, which is open atits top and forms .1 the chamber in .which "the e gs are cooked. Hinged at 5 to the rear on of the casing isa lid 6, which is normally held open I by the action-of an extensible spring 7 connecting the lid to the rear-of its hinge-connection w1th an attachment 8 at some suitable place on-the casin .The tension of this spring is convenient y adjusted by means of astrap extension.- 7 thereto,'having a plu-' rahty of apertures 7",which may be indi- -vi dual.ly en aged, according to the desired e protruding end of attachment tension, to t A Specification of Letters Patent. Application filed May 8,1905. Serial No. 2 59.275.

'is the egg-receptacle, co'nstrueted of woven wire or gauzeslde and end walls. and

provided with a similar horizontal partition 9,'-'which is removably -secured therein at various predetermined heights by having its ends engaged in thenotched'plates 10, attached, to the wallsof the receptacle, thus ermitting'the space therebelow. to be reguv ated for accommodating the number of'eg s to be cooked. This egg-receptacle is fixedly secured within a driptray 1 1, which is hinged 'by pivots 12 to the casing in proximity to the forward jendof chamber 4 and is provided with forwardly projecting ears 13', which are engaged when in the closed p'ositionlsee Fig.

of said spring the egg-receptacle 1s tilted forwardlyby the ro'd 14 into position shown in :3) by a looped rod '14, carried by the lid, and when the latter is thrownl open bythe action I 15, which is engaged when the lid isclosed by the tr1 ger-arm 17 of a lever 17 which is fulcrume I at 18' to suitable'framework within compartment '3. When the lid is closed, the

bent rod 15 passes behind the hinged arm 16,

and this arm is thendepressed to the position shown indotted'lines n'Fig. 3 of the drawing's and engaged by the trigger-arm 1 7 of the lever-17, and the lever 17"1sinturn engaged f at'its lower end by an abutment 19, the con- 1 struction and operation of which will hereinafter be. more fully described. When the 9 oi lid is engaged by these devices, the action of f parts, which I will 'now' des'cribe with referenee the spring 7 tends to swing the longer 'arm bf 1 the lever 17 toward the'rear and a ainst' the j slidable abutment 19,seated in gui eway'20.

and an inwardl disposed flange .24 of; the other spindle. rov ded upon the inner end of spindle 24 is a cross-barf 26, having horns 26, adapted to be engaged with the teeth of wheel 22, and a cam comprised of a concentric portion 27 and an eccentric portion 27 is l formed or rovided u on. the hollow spindle I immediate yfbelowsald abutment 1 28 is a spring tending to press the abut;

tween a head. 23 of'the first-named spindle f rovided on the end of the lid is 'a'bent rod.

-ment 19 downwardly againstthe cam, so that 29, corresponding with the time. for which it the isdesired to retan. the eggs in the cookingwater, the camwill have rotated in the direction indicated by arrow. in Fig. 4 to bring the face 27" of the cam beyond the abutment 19, which is then forced down by the spring 28, permitting the leverarm 17 to swing, thereby releasing the hinged arm 16 from engagement with thetrigger-arm 17 of the lever 17 and releasing the lid, which is opened, as aforesaid, by spring 7 and simultaneously throws'the egg-receptacle out of the waterby pull which is exerted upon ears 13 by the loop-rod 14 as the lidis raised by the spring. While this opening movement is being effected, a spring 30, attached to the said lever 17 anda lug 31 of the casing,'returns the lever in the position shown in Fig. 4, and a bell-crank 32, fulcrumed at 32, is then caused by the however, for setting push-bar 33, connected to the lid, to press upwardly against the action of spring 30 to raise the abutment out of contact with the cam and allow the latter being turned .in either direction for resetting, It is necessary, the device to withdraw the horns 26 out of engagement with the wheel 22, which is accomplished by a triangular-shaped attachment 34 of the bar 33 being forced against a spring 35 and wedgin the ower en of the same outwardly an which in turn moves the spindle, carrying the cross-bar 26 therewith, against the action of the weaker spring 25 by bearing upon a collar 24 of this spindle. The bar 33 acts upon the said bell-crank and the spring 35 only during the last portion of the opening movement of the lid, and to avoidiionfusion in thedrawn,%s I illustrate the positions of these parts 111 igs. 4 and 5 just prior to such engagement.

Included in 'the invention are means for stopping therunning of the clockwork coincidently with and'actuated by the opening of the lid, said means consisting 'of a rod 36, ex-

' tending into the casing from the front end and moved into the line of motion of a'crankp n 37 in the rim of the balance-wheel 37 of said clockwork through the opening mov v -ment of the lid, to which it is operatively conance wheel acts 6o nected by a drag-rod the rod 36 is bifurcated and has hinged thereto and within the slot a tiltable piece 39, having forwardl -pro ectin fingers 39 39', respectively, a

ove and be ow the rod and proecting forwardly of the slot therein. (See Fig. 6.) The spring which actuates this bal- ,to impart a partial rotation in thedlrection of the arrow in this view, and the resilience or reaction of the spring causes the wheel to" reverse and make a par-- tial rotation in the opposite direction, as is common to spring-actuated balance-wheels.

Consequently when the piece 39 is moved 38. The inner end of invention or sacrificing its ping the clockwork with the spring of the balance wheel in tension and enabling the clock mechanism being instantly started when the rod is withdrawn. The drag-rod 38 is formed with a bend 38' and'has its end hooked in a slot 36 of the rod 36 and automatically moves the latter into position to stop the works, as above mentioned, when the lid is opened and may, if desired, be also connected thereto, so as to move the rod outwardly for starting the works automatically when the lid is closed; but Iprefer'to have the same started independently by the o erator, as oftentimes it may be desirable toc ose the lid without causing the unwinding of the m ainspring of the clockwork. The clock is wound by a key 40 upon the mainspring-spindle.

In operation the compartment a being first partly filled with boili water and the eggs to be cooked laced in tIie receptacle 9 when in its inverte position and with the partition secured in same, the fin er 29 is then turned around to register the numeral on the dial designating the length of time which it is desired to cook the eggs. The egg-receptacle is then turned over and into the water-compartment, the operator then closing the lid and throwing the arm 16 backwardl and engaging the free end of the same witht e trigger-arm 17 of the lever 7 and at the. same time. with the other han starting the clock mechanism to operate by withdrawing from the balance-wheel thereof the stop device. When the eg shave been retained in the water a len th 0? time indicated by the dial-mark to whic set, the mechanism within the case will, as before described, release the lid from its fastening, when the 'sprin 7 will cause the same to be thrown back wit suffi- "cient momentum to throw the egg-receptacle upwardly and over into the position shown in Fig. 1. I v p The invention is extremely useful, reliable in action, andadapted to accomplish the purposes for which intended.

I do not wish to limit myself to the specific devices herein described and illustrated, as chan es can obviousl be made in the details wit out departing From the spirit of the advantages. 4 Having described my invention, what I 'claim as new, and desire to secure by Letters Patent, is k a 1.
